Zdravim,
dneska mi prisla kamera Panasonic sd900. Samozrejme, softver dodavany ku kamere je iba pre windows, takze tadialto cesta nevedie. Chcel by som sa spytat, ci ma niekto skusenosti s konvertovanim, zalohovanim videi z kamery na disk vo vysokom rozliseni. Samozrejme, pripojit kameru alebo kartu, skopirovat, ci prehrat je jednoduche. Mna skor zaujima vyber formatu, ktory by bol najviac rozsireny a teda by nebol problem prehravat na nasej LG z usb disku, ci na Samsungu rodicov a podobne. Mozno chcem vela, ale nechce sa mi pre kazde zariadenie daky iny format vyberat a podobne. Skratka, ak ma niekto skusenosti, alebo vie, na co si dat pozor, hocako trivialne by to malo zniet, tak nech mi da vediet prosim.
Dakujem vopred.

K vyssie uvedenemu vypisu musim poznamenat, ze nutne treba zmenit demuxer mpegts na demuxer lavf, inak sa video nezobrazi a to aj napriek tomu, ze v uvode hlasi TS file detected.
Uz hladam poslednych par dni riesenie, ale zatial viac menej bezuspesne. Teda, zistil som, ze by malo stacit zmenit kontajner na mkv a malo by to ist. Takze som to skusil a vysledok je takyto:

Na pc to prehram bezproblemov, ale na tv LG 26LH2000 uz nie, aj ked maju podporu pre mkv. LG26LH2000 ma usb iba pre servisne ucely, ale sa mi to podarilo rozchodit aj na prehravanie multimedialneho obsahu (fotky, hudbu, video) a kedze vyssie uhlopriecky tej istej rady to podporuju vo vychodzom stave, tak si nemyslim, ze by bol prave problem v tv. Ak spustim subor na tv, tak ho nacita, ale obraz sa zasekne na uvodnej snimke bez zvuku tiez, aj ked casomiera videa ide dalej.
Skusam dalej, ale ak by predsa len niekto mal chvilku casu a pozrel, napisal cokolvek, skusenosti ci nazor, ako dalej, tak budem velmi vdacny.
Dakujem.

Dakujem za pomoc. Po mnohych upravach rozlisenia a snimkovacej frekvencie a skusania prehratia daneho suboru som zistil nasledovne. LG 26lh2000 a dovolim si tvrdit, ze prinajmensom dana generacia tv je nepouzitelna na prehravania fullhd videi pri 50 snimkoch za sekundu. Ono, ani manual neklame, kde je jasne napisane, ze bud fullhd a 25 snimkov za sekundu alebo 1280x720 pri 50 snimkoch za sekundu. Inak hlasi chybny subor a neprehra ho.
Skusal som aj nizsie rozlisenia a pri 50 snimkoch za sekundu prehra len malicko cez 1280x720. Ale tento tv ma osobne az tak netrapi, skor ma zaujima Samsung D6100, ci bude schopny to prehrat priamo z usb pri fullhd a 50 snimkoch, aj ked oni tvrdia, ze podporuju do profilu 4.1 high (up to 4.1, co zjavne treba chapat tak, ze o 4.1 mozem snivat vzhladom na bitrate, ale ved necham sa prekvapit) pri h.264 v mkv kontajneri, ale bitrate az do 25 mbit/s,Navyse je v manuale poznamka, ze podporuje usb hdd, ale nie usb hdd raid pole, co isto coskoro zistim, az pridu disky konecne, bo tu mam icy box pre dva disky s moznostou RAID 0 a RAID1 alebo ako JBOD.
Coraz castejsie mam dojem, ze si tu niekto robi srandu.
Takze mam taky dojem, ze bez dakej krabice pod telkou sa clovek este nezaobide a ked pride ten cas, tak marketing opat raz pohladi na dusi a da to jasne najavo.
Kazdopadne dakujem MadCatX za snahu pomoct a koniec koncov ma to aj posunulo spravnym smerom, takze pomoc to bola isto. ;)
